Interact.jl allows you to use interactive widgets such as sliders, dropdowns and checkboxes to play with your Julia code.
To install Interact, run the following command in the Julia REPL:
Pkg.add("Interact")
Note: if you have IPython 3.0 installed, check out the master version:
Pkg.checkout("Interact")
To start using it in an IJulia notebook, include it:
using Interact
GtkInteract provides Gtk support for Interact, letting you use tools like Winston for plotting.
The best way to learn to use the interactive widgets is to try out the example notebooks in the doc/notebooks/ directory. Start up IJulia from doc/notebooks/:
ipython notebook --profile julia
Interact needs IJulia to be running on Jupyter/IPython 3.0
